Use the commutative property to find the unknown numberin the equation 35x70=mx35

 70

Step-by-step explanation:

The commutative property of multiplication says that when we find a product of two numbers then it does not matter which number we write first or second.

i.e. the order of writing numbers in a product doesn't matter here.

The answer remains the exactly same.

i.e.    , where a,b are integers.

The given equation :

We can see that there is 30 in both sides , then by using commutative property of multiplication, 'm' should be 70.

hence, the unknown number : m= 70

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
